Would appreciate some feedback on the questions below. Thanks
If you have a 4 bbl kick in DP and a 4 bbl kick in casing, what happens to SICP and SIDPP?
DP off bottom and no float in string, SICP = 300 psi. What happens to SIDPP?
What would you do if you had multiple kick in the well?
What would you do if you took a kick while displacing cement?
Hi Dave, thanks for the questions, information provided by Steve Devereux (CEO Drillers.com and industry expert) :
- If you had a gas influx which entered the drillpipe AND the annulus with the same volume, SIDPP would be higher than SICP. I have to say that this would be an almost impossible scenario. However to answer the question, the BHP would be the same for both DP and annulus, so the surface pressures depend on the hydrostatic pressures in the pipe and annulus respectively.
- This is a swabbed kick. If the kick is below the bit, then SICP = SIDPP.
- Multiple separate influxes; better to use Drillers method to get the influxes out then circulate in kill weight mud.
- This would be a complex situation without a simple answer. If the top plug has been dropped then of course the influx cannot be circulated out. Initial action will be to close in the well. Probably control volumetrically to get the influx out.
Thanks for contributing, keep sharing your thoughts!
